JOURNAL-BEARING FOR CARS- I SPECIFICATION forming part of Letters Patent No.'761,903, dated June '7, 1904.

Application filed geptember 10, 1903- Serial No. 172,680. (No model.)

to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in journal-bearings for cars or other like vehicles. It consists of certain improvements in means for lubricating the journal-bearings and for preventing the access of dust, grit, or the like to the same and also to keep the said journalbearings from heating when in use.

My invention will be understood by reference to the accompanying drawings, in which the same parts are indicated by the same letters throughout the several views.

Figure 1 is a'vertical section through the car-Wheel and journal-box and shows the axle in elevation. Fig. 2 is a section along the line 2 2 of Fig. 1, parts of the inner face of the journal-box being broken away. Fig. 3 is an end view, and Fig. 4 a plan, ofthe invention:-

A represents a car-axle having the usual skein or bearing. On the axle the wheel B is secured in the usual way, and the said skein supports the usual bearing-blocks, as shown in Fig. 1. V

C represents the journal-box, above which the car-springs (not shown) are secured, which box is preferably flanged, as at 0, to which flanges the Water-compartment D is secured, as by suitable bolts (Z. The journal-box C is provided With an overflow passage 0, controlled by a faucet e, and it is also provided with a filling-pipe F, preferably closed by a cap f. The compartments 0 and D are connected by the pipe H, which may be closed by the cock 7b. The'top of the. compartment D is closed, preferably, with a screw-plug g. The inner head C of the journal-box has attached thereto a slotted plate 0 which slips over the axle and in which travels the two shutters '5 and i, which are provided with projecting arms 7?, which are connected together by the springs c', which springs are so adjusted 'as to keep the shutters 2' and z" tightly against the periphery of the axle A and prevent the escape of the lubricant from the journal-box. The plate (J is secured to the head 0 of the journal-box by means of the bolts 0 (Shown in dotted lines in Fig; 2.) In practice the operation of the device is as follows: The parts being in the position shown in Fig. 1, with the cap f removed from the pipe F, Water is poured into the box 0 until it begins to overflow through the outlet c. Then the faucet e is closed, and the box C is filled with oil until-theoil rises up in the pipe F. Now unscrew the plug 9 and fill the Water-compartment D With water. Then open the cook it, which will normally be left open except when refillingthe journal-box with lubricant. 1t will be seen that the upper part of the skein of the axle will be immersed in oil and the lower part in water, and the water from the compartment D will flow in past the cock, compensating for any unavoidable waste of fluid in the journal-box, and thus rendering it only necessary to fill up the journal-box with lubricant at long intervals. By using oil on top of the skein and water beneath, as shown,

the parts are kept well lubricated and also off the journal-bearings and prevents hot boxes. A small hole should preferably be provided in the top of the cap f, as shown in Fig. 4:, to allow of the escape of any steam that maybe formed if the friction should by any accident become excessive. The shutters should be lubricated preferably with some thick gum lubricant as a further protection against the escape of fluid from the journalbox. In cold weather instead of Water a mixture of water and glycerin may be used. As is Well known, such a mixture will not freeze except under extremely low tempertures, such as are not ordinarily experienced in the United States or its Territories. I I do not mean to confine the invention to the precise details of construction, as various modifications might be made which could be used without departing from the spirit of my invention.

Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States, is

1. In a journal-bearing for the axles of cars or the like vehicles, the combination with a Water-tight journal-box adapted to inclose the skein of the axle, and a supply-compartment for the Water connected thereto, said compartment extending above the top of the journal-box and opening into said box near its base, of means for feeding oil to the top of said box, and means for preventing the es cape of fluid therefrom, substantially as described.

2. In a journal-bearing for the axles of cars or like vehicles, the combination With a closed journal-box, of means engaging the axle and preventing the escape of fluid from said box, a Water-compartment provided with a connecting-pipe opening into said box, a cock controlling said opening, and means for feeding oil and Water to said box, substantially as described.

3. In a journal-bearing for the axles of cars or the like vehicles, the combination with a Water-tight journal-box adapted to inclose the skein of the axle, and a supplycompartmcnt for the Water connected to said box, said compartment extending above the top of the journal-box and opening into said box near its base; of means for feeding fluid to the top of said box, and means normally engaging the axle and preventing the escape of fluid therefrom, substantially as described.

4. In a journal-bearing for the axles of cars or like vehicles, the combination With a closed journal-box, a guard engaging the axle and preventing the escape of fluid from said box, and a Water-compartment provided with an opening into said box near its base and extending above the top of said box, of means for feeding oil and Water to said box, substantially as described.

5. In a journal-bearing for the axles of cars or like vehicles, the combination with a closed journal-box, and a guard engaging the axle and preventing the escape of fluid from said box, of a Water-compartment secured at the outer end of said box and projecting above the same and provided near its bottom With an opening into said box, a cock controlling said opening, and means for feeding oil and Water to said box, substantially as described.

6. In a journal-bearing for the axles of cars or the like vehicles, the combination with a Water-tight journal-box adapted to inclose the skein of the axle, of a supply-compartment for the Water connected to said' box, an outlet to the air provided at somedistance above the bottom of said box, With means for closing same When desired, and means for feeding fluid to said box, substantially as described.

7. In ajournal-bearing for the axles of cars or like vehicles, the combination With a closed journal-box, and a guard engaging the axle and preventing the escape of fluid from said box, of a \vater-compartnlent secured at the outer end of said box and projecting above the same and provided with an opening into said box near its base, and means for feeding oil and Water to said box, substantially asdescribed.

11. In ajournal-bearing for the axles of cars or like vehicles, the combination with a closed journal-box, a guard engaging the axle and preventing the escape of fluid from said box along the axle, a water-compartment secured at the outer end of said box and projecting above the same and provided with an opening into said box near its base, and an inletpipe in the top of saidbox, and provided with a perforated cap, substantially as described.
